To all whom t may concern.'

Be it known that I, JOHN citizen of the United States, residing at Brooklymin the county of Kings andl atate of New York, have invented `new and useful hnprovements in Passenger Conveyances, of which the followingis a speciication.

rlhis. invention relates to passenger sonveyances.

Some of the objects of the invention are: to equi-p a passenger conveyance with an apparatus which will permit its being o'aerated successfully by one man;V to equip a passengerconveyance with an apparatus so that passengers may be taken on and are permitted toy get off Without crowding and the cbviation ofcongestion;` to provide an apparatus for a passenger convey-ance which permits passengers to enter the conveyance atv-the front-endA and permits of their exit at therear endl and` prevents their entrance through the exit, the saidI apparatus embodying among' other things-'a visualsignal anda mov-able step, which step is actuated by a passengerto operate the signal for the starting ofthe conveyance.

'l/Vith these and other objectsinv view the invention resides in the arrangement and combination of elements hereinafter more fully described andr illustrated in the accempanyingk drawings,y in which 1'- n Figure 1is=asectional diagrammaticfview illustratingl certain features of the present invention.V

As stated, the present invention'contemplates the equipping of a passengerconveyance with an apparatus permitting the conveyance to be operated successfullyv by one man. The passenger compartment, in accordance with this invention is to be provided with a plurality of entrances and a `plurality ofl exits. An entrance and an exit i). ENGEL, a

are arranged at eachv side of the compartment with. the entrancel at the front end ofthe compartment and the exit occurring at the rear end thereof. The apparatus for controlling the entrance and the exits is such as to permit the conveyance tobe operated from either end and the apparatus embodies two. identical mechanisms. For the salte of convenience the following explanation will be. limited to but a single mechanism complete in itself for controlling the entrance and enit of passengers when the car is traveling in a particular direction.

Referring now to the drawing, it will be seen that the conveyance will include a passenger compartment 10 having at each side an entrance 11 and an exit 12.k The exit 12-is normally closed by a door 13. which moves on a vertical pivot 14. Arranged with respect to the door 13 is a step 15 arranged for movement onstub shafts 1-5a to a raised and lowered position. The step being .in a raised position when the door13 is closed and is adaptedl t0 be disposed in its lowered position when the door 13 is in anI open' position. The turnstile 1G is airanged in proximity to the exitl 12. The turnstile comprises sets of radially extending obstruct-ing pivoted arms which are arranged in superposed groups. he turnstle may be rotated in one direction only so as to permit the exit to passengers but prevents entrance at. the exit 12. Y

ln order to permit of the exit of passengers at the eXit 12, the door 13 is opened outwardly and the step 15 is lowered simultaneously with the opening of the door 13 and such action is accomplished by the devices presently described. A vertically disposed shaft 17 mounted in suitable bearings has secured to the upper end thereof an operating handle 18 vand the lower end of said shaft-is provided with a pinion 19. The pinion 19 meshes with teeth 20 of a rod 21 which extends lengthwise of the compartment 10 atthe undersidethereof.1 The teeth 20of the rod 21 are held in mesh with the teeth of the pinion 19 by the employment of an idler pinion 22 which meshes with teeth 23 of the rod 21. llt is to be understood that any other suitable means in lieu of the pinion 22 and the teeth 23 may be used to prevent( the displacement ofthe rod 21p. The-rod 21 is provided with teeth 24 which mesh with a pinion 4,25 which meshes with a pinion 26 at the lower end of the door pivot 14. An idler pinion 27 which meshes with teeth 28 of the rod 21 is employed for maintaining an operative relation between the teeth 24 and the teeth of the pinion 25. The free end of the rod 21 has connection with an arm 29 by the employment or a ball and socket joint 30, and this arm 29 is connected to a bar 31 in a manner so as to have movement with respect thereto. The step 15 is provided with arms 32 which have their free ends in securement with the bar 31. It will now be manifest upon proper manipulation of the handle 18, the rod 21 will be moved and through intervention of the pinions 25 and 26, the door 13 will be made to swing outwardly to an open position and, at the same time the step 15 will be lowered, due to the fact that the varm 29 will be moved along the bar 31 until the part surrounding the bar 31 encounters the upper end of the arm 32 ad bar 31 will move along it until it encounters the pin 34 secured to the bar 31. This latter action is supplemented by weights 35.

The turnstile 16, as stated, may be rotated in one direction only and embodies upper and lower groups of arms 36. The upper groups or arms 36 have pin and slot connection 37 with vertically disposed bars 38 supported by an upper member 39 and an intermediate member 40 secured to a central shaft 41 mounted in supports 42. The lower groups of arms 36 have pin and slot connection 43 with vertically disposed bars 44 supported by the member 40 and a lower member 45. The inner ends of the upper groupsof arms 36 have pivotal connection with movable bars 46. The bars 46 move in guide openings in the members 39 and 40. The upper end of each of the bars 46 is provided with a roller 47 each of which is held in contacting relation with a cam surface 48 by a compression spring 49 interposed between a pin 50 secured to the shaft 41 and the member 39. The inner ends of the lower groups of arms 36 are pivoted to movable bars 51. The bars 51 move in guide openings in the members 40 at 45 and the lower end of each bar 51 is provided with a roller 52. Each roller 52 is held in contacting relation with a cam surface 53 by a spring 56 interposed between a pin 57 secured to the bar 51 and the member 45. `It will now be manifest that in moving the arms 36 ina clockwise direction they will be made to move in a collapsed condition, immediately they have passed the exit opening. The upper groups or arms 36 will be moved downwardly in an inclined ,position and the lower groups of arms 36 will be moved upwardly to an inclined position. The object of collapsing the arms 36 is to give more space in the compartment 10 and at the same time, under the present arrangement, the ceiling of the compartment 10 will notinterfere with the collapsing or the arms, the uppermost of which' are in close proximity thereto. The cam surfaces 48 and 53 are such as to move the arms 36 to obstructingV positions immediately before they arrive at the eXit opening. A gravity pawl 58 and a ratchet 59 prevent the turnstile from rotating in a counterclockwise direction.

In order that the operator of' the conveyance may be apprised ofthe exit of the passenger or passengers at a particular point to start the conveyance a visual signal is employed This signal consists of an electric lamp arranged in a circuit having a suitable source of electrical energy and a circuit closer which is arranged upon the wing` 33 and is actuated by the step 15. When the step 15 is arranged in a lowered position, a slight shifting or the arm 2,9 by the manipulation of the operating handle 18 permits a slight upward movement of the step 15, so that as the weight of the passenger is removed vfrom the step 15 the weights 35 will cause the step 15 to actuate the circuit closer 61 to thus light the lamp 60. When the lamp 60 remains lighted for what will be an unusual length. of time, this will be the signal to start the conveyance.

While there has been shown the preferred embodiment of my invention, it is to be understood that the right is reserved to make any and all necessary changes, alterations and modifications within the scope of the claims hereunto appended.

What is claimed as new is 1. A passenger conveyance as characterized, including a passenger compartment having entrances and exits, in combination with an apparatus including a correlated door and movable step at each exit,`means for actuating said doors and steps simultaneously for permitting the entrance of passengersto the compartment and their exit therefrom through said exits but preventing their entrance through saidexits, and visual signal means, actuated upon the upward movement of said steps.

2. A passenger conveyance as characterized, including a passenger compartment having entrances and exits, in combination with an apparatus including a correlated door and movable step at each exit, means :for opening the doors and for lowering the steps simultaneously for permitting the entrance of passengers to the compartment and their exit therefrom through said exits but preventing their entrance through said exits, and visual signal means, actuated by either of said steps upon their upward movement.

3. A passenger conveyance as characterized, including a passenger compartment 4having an entrance and an exit, a turnstile arranged adjacent the exit, a door normally closing said exit, a step varranged at said exit in relation to said door, and means operative for eiiecting the opening of the door and the lowering of the step to permit exit of passengers.
